2 Claims.

The invention relates to baling presses and refers more particularly to baling presses of that type in which a plurality of linear members are connected to the compressing plunger to move the same during its compressing stroke.

The invention has for one of its objects the provision of an improved connection for moving the compressing plunger inopposite directions. The invention has for another of its objects the provision or" means for distributing and more especially equalizing the stresses between the linear members of the connection.

With these and other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully'hereinafter set forth.

In the drawing:

Figure 1 is a perspective view of a baling press embodying my invention; a

Figure 2 is a front elevation thereof with parts broken away for clearness of illustration;

Figure 3 is an end elevation thereof with parts broken away for clearness of illustration.

As illustrated in the present instance, the baling press is of the down-stroke type and comprises the vertically extending baling chamber 8, the stationary platen 2 within the lower end of the baling chamber and the plunger 3 movable within the baling chamber toward and away from the platen and also adapted to move upwardly through the open top of the baling chamber and to assume a tilted position therebeyond. The lower portion of the baling chamber is formed by the pivoted clam shell doors 4 and the stationary end wall 5, the doors each having a portion forming a side wall of the chamber and a transverse portion forming a part of an end wall of the chamber opposite the end wall 5. The transverse portions terminate a sufficient distance from each other to provide in effect a vertically extending slot centrally oi the chamber. The end wall 5 extends throughout the height of the baling' chamber and is provided with a corresponding slot. The upper portion of the baling chamber has its end wall opposite the end wall 5 also provided with a slot registering with the slot formed by the transverse door portions.

The plunger 3 has the beam 6, the ends of which are adapted to extend through the slots formed in the end walls of the baling chamber for connection to the flexible connections I, there being one of each beyond each end of the baling chamber. Each flexible connection is reeved over the upper sheave B and the lower sheave 9, the lower sheaves being preferably upon the same shaft I!) which is adapted to be driven by means of the prime mover I! through the intermediary of the gearing l2. The prime mover is preferably an electric motor and the gearing is preferably of the change-speed type.

Each flexible connection has the portion 13 which comprises the plurality (two, as shown) of linear members M, which are'in the nature of chains and which are reeved over the lower sheave i 9 and are adapted to extend over the upper sheave 8. Each flexible connection also has the portion which comprises-the single linear member it, which may be a chain vor 2. cable, and which is connected atone end to the adjacent end of the beam 6.- Each flexible connection also has the evener connections at the ends of its portion 13 and connected to the adjacent end of the beam 5 and the single linear member. l6 of the portion I5. The evener connection between the linear members M and the beam 6 comprises the evener bar I! connected at its ends to the linear members and the link l8 connected atzone end to the adjacent end of the beam and at the opposite end to the evener bar equidistant between its points of connection to the linear members, The other evener connection comprises the evener bar l9 connected at its ends to the linear members l4 and also connected to the linear member it equidistant between itspoints of connection to the linear members l4.

Both the upper sheaves 8 and the lower sheaves 9 are multiple sheaves. Each upper sheave has, as shown, the outer heave portions and the intermediate sheave portion 2!, the linear members It. being adapted to extend over the outer sheave portions and the link it and the linear member 16 being adapted to extend over the intermediate sheave portion during operation of the press. It will be noted that the evener bar I! is adapted to pass over all of the sheave portions. Each lower sheave has, as shown, the pair of sheave portions 22 which are spaced apart to receive the linear members l4 and which are preferably integral so that they will be driven in unison.

It will be noted that with this construction powerful connections for moving the plunger during its compressing stroke toward the platen may be readily provided by forming the advancing portions of these connections of a plurality of linear members and an evener connection for distributing the stresses so that each linear member will do its proper amount of work. It will also be noted that the portions of the flexible members for returning the plunger are made less powerful since much less work is required of them. It will be further noted that the sheaves over which the flexible connections are reeved are formed to receive the parts of the flexible connections adapted to extend over these sheaves so that they do not interfere with the desired op eration of the press.

What I claim as my invention is:

1. In a baling press of the down-stroke type,

a baling chamber open at its upper end, a stationary platen in the lower portion of the chamber, a movable platen above the stationary platen adapted to be moved relative to the stationary platen and to be extended beyond the open upper end of the chamber in tilted position to facilitate loading, a drive shaft below the chamber, a. pair of drive sheaves secured to said shaft at opposite sides of the chamber, each of said drive sheaves having a pair of axially spaced peripheral grooves, a second shaft above the open upper end of the chamber, a pair of idler sheaves upon said second shaft at opposite sides of the chamber, each of said idler sheaves having a pair of axially spaced peripheral grooves in vertical alignment with the peripheral grooves in the drive sheave at the same side of the chamber and a peripheral groove intermediate said pair of axially spaced grooves, connections at opposite sides of the chamber for driving the movable platen, each of said connections comprising an evener bar operatively connected to the movable platen, a pair of liner drive members connected to said evener bar and reeved over the drive sheave, a second evener bar connected to the other ends of said linear drive members, a single linear member connected to said second evenerbar and reeved over the intermediate peripheral groove in the idler sheave and connected at its other end to the movable platen, and driving means operatively connected to said drive shaft to tension said pairs of linear drive members and to pull the movable platen downwardly to compress the bale, said driving means being adapted to drive said drive shaft in the opposite direction of rotation to tension said single linear members to move the movable platen and said first mentioned evener bars a substantial distance around the periphery of the idler sheaves to thereby move said movable platen beyond the open upper end of the chamber to tilted position.

2. In a baling press of the down-stroke type, a baling chamber open at its upper end and having opposite side walls provided with aligned vertically extending slots located centrally thereof, a stationary horizontal platen in the lower portion of the chamber, a movable platen adapted to be moved between the stationary platen and the open upper end of the chamber and to be extended beyond the upper end of the chamber in tilted position, a beam secured to the movable platen and having its ends projecting through the vertical slots in the sides of the chamber, a drive shaft below the chamber, a drive sheave secured to each end of the drive shaft beyond the sides of the chamber, each of said drive sheaves having a pair of axially spaced peripheral grooves, a second shaft above the open upper end of the chamber, an idler sheave upon each end of said second shaft beyond the sides of the chamber, each of said idler sheaves having a pair of axially spaced peripheral grooves in vertical alignment with the peripheral grooves in the drive sheave at the same side of the chamber and a peripheral groove intermediate said pair of axially spaced grooves, connections at opposite sides of the chamber for driving the movable platen, each of said connections comprising an evener bar operatively connected to the projecting end of the beam, a pair of drive chains connected to said evener bar and reeved over the drive sheave, a second evener bar connected to the other ends of said drive chains, a single linear member connected to said second evener bar and reeved over the intermediate peripheral groove in the idler sheave and connected at its other end to the projecting end of the beam, and driving means operatively connected to said drive shaft to tension said drive chains and to pull the movable platen downwardly to compress the bale, said driving means being adapted to drive said drive shaft in the opposite direction of rotation to tension said single linear members to move the movable platen and said first mentioned evener bars a substantial distance around the periphery of the idler sheaves to thereby move said movable platen beyond the open upper end of the chamber to tilted position.
